Application led March 8, 1921. Serial No. 450,777.

1 0 vertible either as a cooker or radiator such' as occasionmay require.

The main object of the invention is to provide a convertible device of the above character that isetlicient in operation, compact and durable and which may be manufactured at a reasonable cost.

Aside from being used as a cooker proper, that is for broiling, frying, etc., the device may be used and is especially designed as a tireless cooker, the initial heat being furnished through the instrumentality of a coil of electrical resistance wire.

Various other objects and advantages of my invention will become apparent during the continuance of the following description.

In the drawing:

' Figure 1 is a view front elevation showing'my invention as its preferred embodiment/ ,t

Figure 2 is a view` in vertical central section of the device taken on line 2-2 of Figure 1.

- A Figure 3 is a view in horizontal cross section `taken on line 3--3 of Figure 1.

My invention consists generally of a body or housing portion 10 of suitable shape and dimensions that is preferably constructed of metal. In its front face the body portion 10 is provided with a door opening 11 and about this o ening is arranged an inwardly projecting ange 12. 'A door 13 is swung upon hinges 14 which are in turn mounted on the body 10 and is adapted to close the opening 11, the door. consisting generally of a metallic body y15 having inwardly projecting flanges 16 along its vertical and horizontal e ges, as clearly sho'wn in Figure 2.

In order to maintain the door in a secure position when closed I provide the same with pivoted handles 17 which are designed to be engaged with lugs 18 of the body portion coiled resistance wire 21.

.provided with an opening 22 which commu- Y 10. l/Vhile this particular form of securing means is herein illustrated it is pointed out that I do not wish to limit myself in that respect and, therefore, that other types of means may besubstituted if so desired.

Within the bottom of the body 10 and below the lower edge of the opening 11 I provide a comparatively thick disc 19 of insulating material of any desired form. In

the upper face of this disc is cut a tortuous channel or way 20 for the reception of a nicates with the channel or way 20 and a plug socket 23 of the body portion 10. Therefore the ends of the wire 21 are passed through 'the opening 22 and fasten to the socket 24 that has connection with a suitable source of electrical power by lmeans of the wire 25. While I do not wish to limit myself to the specific material'used in the -construction of the disc 19 it is pointed out for sak ofV illustration that soapstone may, be use The inner wall of the bod the door 13 is lined with a Iieavy coating of insulating material in order to confine the heat within the body portion. The insulating material which covers the inside of the body portion 10 including thetop thereof is designated by the numeral 26 while the insulating material of they door is designated by the .numeral 27.

In order to allow for the escape of steam from the interior of the body portion I provide a suitable air vent 28 in the tgp of the body portion 10 such as shown in 1g'ure2. When the device is used as a reless cooker the door 13 is of course closed-but when used as a radiator orheater the door is o ened so that the heat from the interior wi radiate into the'room or other place in'which the device is situated. l

What is claimed is: Avreless cooker and heatercomprisin a housing closed at its top and bottom ut having an opening in the side,` the said top and side walls of the housing having a facing of insulating material, an insulating disc covering the inside bottom of the housing and having its upper face provided with a The disc is alsoportion 10 and tortuous v channel presenting exposed arcs In testimony whereof I aix my signature concentric with the center of the said dise, in presence of two Witnesses.
